About Converting Drams per Cup to Pounds per Pint
Dram per Cup and Pound per Pint both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
pounds per pint = drams per cup × 0.0078125
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 pound per pint equals 958.611418535 base units, so dividing one by the other gives the direct dram per cup-to-pound per pint factor of 0.0078125.
Simple example
1 dr/cup × 0.0078125 = 0.0078125 lb/pt
1 dram per cup = 0.0078125 pounds per pint.
Real-world example
1,000 dr/cup × 0.0078125 = 7.8125 lb/pt
1,000 drams per cup = 7.8125 pounds per pint.

How do I convert pound per pint back to dram per cup?
Use the reverse factor: 1 pound per pint equals 128 drams per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
What is a pound per pint?
Pound per Pint (lb/pt) is a unit of density.
Is the dram per cup to pound per pint conversion exact?
Yes. Both dram per cup and pound per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.0078125 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
